Description

Technical Field

[0002] Plastic woven bags, also known as snake skin bags, generally refer to packaging materials mainly made of polypropylene. They are made by extruding, stretching into flat filaments, and then weaving, knitting, and bag-making. The process of preparing and forming plastic woven bags mainly refers to the process of crushing raw materials, heating and softening them, extruding, stretching into flat filaments, and weaving into tubular tapes.

[0003] When the existing woven bag production and processing equipment is in use, it is difficult to completely crush the raw materials. The uncompletely crushed raw materials are difficult to be crushed multiple times, and the crushing effect is poor. When the raw materials are crushed into smaller pieces, manual operation is required to start the heating equipment to heat and soften the smaller raw materials, which is time-consuming and laborious, with low work efficiency and low automation. After the smaller raw materials are heated and softened, manual operation is still required to put them into the extrusion equipment for extrusion, making it difficult to carry out continuous processing. The connection between equipment is not compact and it is inconvenient to use. Summary of the Invention

[0019] When the present invention is in use, start the crushing motor 4. By setting the first rotating shaft 23, the crushing roller 24 and the first crushing knife 25 rotate. Pour the raw materials from the feeding port 5. By setting the baffle 22, the raw materials pass between the crushing roller 24 and the guide plate 40. The rotating first crushing knife 25 and the fixedly arranged second crushing knife 26 cooperate with each other to crush the raw materials. The crushed raw materials slide down along the inclined guide plate 40 onto the filter screen 27. Through the filtration of the filter screen 27, the smaller crushed materials pass through the filter holes and fall onto the receiving plate 32. By making the abutting block 10 closely adjacent to the left outer wall of the box body 1, part of the larger materials that are not completely crushed slide along the surface of the filter screen 27 and gather at the first reciprocating port 28. Start the cylinder 6. By setting the connecting rod 19 and the lifting block 20, the reciprocating block 8 moves downward. The downward movement of the reciprocating block 8 drives the extrusion rod 9 and the rack 11 to move downward. The extrusion rod 9 drives the extrusion sliding plug 39 to move away from the fixed plate 7, so that the hot air in the extrusion cylinder 12 is extruded through the first extrusion pipe 13. The extruded hot air blows on the smaller materials on the receiving plate 32 to soften the smaller raw materials. The downward movement of the rack 11 rotates the gear 14 and the threaded rod 17, and further makes the extrusion plate 34 move towards the electromagnet 37; During the downward movement of the reciprocating block 8, the reciprocating block 8 contacts the abutting block 10 and makes the abutting block 10 move downward accordingly. The downward movement of the abutting block 10 compresses the first spring 18. The downward movement of the abutting block 10 drives the first conductive block 29 to move downward. During the process of the reciprocating block 8 making the abutting block 10 move downward, by setting the reciprocating cavity 21, the larger materials gathered at the first reciprocating port 28 enter the reciprocating cavity 21. When the reciprocating block 8 moves downward to the lowest position, the first conductive block 29 and the second conductive block 30 come into contact with each other, and the circuit of the electromagnet 37 is connected and magnetized. Thus, the magnetic block 38 above the electromagnet 37 is attracted and makes the magnetic block 38 move downward. The telescopic rod 35 retracts, and the second spring 36 is compressed. When the magnetic block 38 moves downward, the receiving plate 32 rotates around the axis of the second rotating shaft 31 due to its own gravity, so that the softened smaller raw materials on the top of the receiving plate 32 slide along the receiving plate 32 and slide between the extrusion plate 34 and the extrusion port 33; Subsequently, the cylinder 6 makes the reciprocating block 8 move upward. Since the reciprocating block 8 is closely adjacent to the left outer wall of the box body 1, the larger raw materials in the reciprocating block 8 will not fall. During the upward movement of the reciprocating block 8, the elastic force generated by the compression of the first spring 18 makes the abutting block 10 move upward accordingly. Then, the first conductive block 29 at the bottom of the abutting block 10 and the second conductive block 30 move away from each other and no longer contact. The circuit of the electromagnet 37 is no longer connected, and the magnetic block 38 is no longer attracted. The elastic force generated by the compression of the second spring 36 makes the magnetic block 38 move upward and return to the initial position. The upward movement of the magnetic block 38 makes the receiving plate 32 rotate around the second rotating shaft 31 in the other direction, and makes the receiving plate 32 return to the horizontal state again; The reciprocating block 8 moves upward, driving the extrusion rod 9 and the rack 11 upward at the same time. The upward movement of the extrusion rod 9 drives the extrusion slide plug 39 upward, so that the hot air in the electric heating box 16 is sucked into the extrusion cylinder 12 through the second extrusion pipe 15, facilitating the heating and softening of the next smaller raw material. The upward movement of the rack 11 causes the gear 14 and the threaded rod 17 to rotate in the other direction, so that the extrusion plate 34 moves away from the electromagnet 37, and the softened smaller raw material that has fallen between the extrusion plate 34 and the extrusion outlet 33 is extruded from the extrusion outlet 33 to complete wire drawing. When the reciprocating block 8 moves upward to the initial position, the reciprocating cavity 21 cooperates with the second reciprocating port 41, so that the larger raw material in the reciprocating cavity 21 passes through the second reciprocating port 41 and then slides down along the surface of the guide plate 40 again to the first crushing knife 25 and the second crushing knife 26 for crushing. Subsequently, the cylinder 6 is used again to make the reciprocating block 8 complete a reciprocating motion, so as to heat and soften the smaller material after secondary crushing and extrude it into wire drawing.

[0020] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
